IMPROVEMENT IN CHIMNEY-TOPS.

Specification forming part of Letters Patent N0. 136,234. dated February 25, 1873.

To all 'whom it may concern:

Be it known that 1, JAMES GoRroN, ofthe city, county, and State of New York, have invented a new and Improved Chimney-Top 5 and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which drawing- Figure 1 represents avertical central section of this invention. Fig. 2 is a horizontal section ofthe same in the planear Fig. l. Fig. 3 is an inverted plan of the top detached.

Similar letters indicate corresponding parts.

This invention relates to a chimney-top, which consists of a conical cap provided with a regulatingspout, and set on an arbor, which central arbor is retained in position by bridges which are sprung into the chimney-line, and which can be easily removed, and a similar removable bridge is sprung into the conical cap, so that when the bridges and the arbor are in position the top can revolve freely, and that by removing said bridges the whole apparatus can be readily taken apart and packed up in a comparatively small compass, the tops being in that case freeto be nested.

In the drawing, the letter A designates the flue of a chimney, on which is placed my top B. This top consists of a conical cap, a., which is provided with a projecting spout, b, closed at the top and wide open at the bottom, and which is set on a central arbor, C, so that it can freely revolve thereon. When the top is exposed to a current of air the spout b acts as a vane, and causes the top to turn on its arbor until the spout is situated on the lee side of said top. By this arrangement the smoke rising up through the Hue A is free to discharge under all circumstances, and without obstruction by gusts of winds or currents of air which may y strike the chimney from any direction.

The central arbor C is stepped in a bridge, c, which is sprung into the ue A, said line being provided with two slots to receive the ends ofthe bridge, which project through the flue, and are provided with holes to receive pins or keys, which serve to retain the bridge firmly in position. A similar bridge, c1, which is inserted into the line A, serves to steady the arbor C; and in the top B is also sprung a bridge, c2, while the upper end of the arbor bears against the interior surface of the apex of the cone a, as shown in Fig. 1. The bridges c1 and c2 are sprung into slots in the flue and top, and secured in position by pins or keys,

in the same manner as the bridge c and when it is desired to pack up my top for storage or transportation I take off the top, remove the bridge c2, take out the arbor C, and remove the bridges c and c1, and I am then enabled to nest the tops and to pack them up in a comparatively small compass. The bridges c, c1, and c2 are easily reinserted Whenever it is desired to put up my chimney-top and the operation of putting up the same can be accomplished with little loss of time by any person of ordinary mechanical skill.

What I claim as new, and desire to secure by Letters Patent, is-

The removable bridges c 0102, secured, as described, in the position shown, in combination with the flue A, conical top B, spout b, and vertical arbor C, all constructed and arranged as herein shown and specified.

JAMES GORTON.
